ClassCastException during deployment with more than one used entity

Hi,

i am still trying to get into NW development and got one more time stuck. I have a CE 7.1 SR5 project containing a dictionary, a bean module, an EAR project and a web dynpro project.

With the following two classes everything runs fine:

[AT]Entity
[AT]Table(name="TMP_USER")
[AT]NamedQueries(value={[AT]NamedQuery(name="doLogin", query="SELECT u FROM User u WHERE u.login = :login AND u.password = :password")})
public class User implements Serializable {
	[AT]Id
	private int id;
	private String login;
	private String password;
	private static final long serialVersionUID = 1L;
	public User() {
		super();
	}
// Omitted Accessors
}

[AT]Stateless(name="UserSessionBean")
[AT]WebService
public class UserSessionBean implements UserSessionLocal 
{
	[AT]PersistenceContext(unitName="DBAccess")
	private EntityManager em;
	
	public User doLogin(String login, String password)
	{
		Query query = em.createNamedQuery("doLogin");
		query.setParameter("login", login);
		query.setParameter("password", password);
		try
		{
			return (User) query.getSingleResult();			
		}
		catch(NoResultException e)
		{
			return null;
		}
	}			
}

build, deploy, run in webservice navigator -> ok

Then i created a new entity:

[AT]Entity
[AT]Table(name="TMP_PROJECT")
[AT]NamedQueries(value={[AT]NamedQuery(name="findAllProjects", query="SELECT p FROM Project p")})
public class Project implements Serializable {
	[AT]Id
	private int id;
	private int ownerid;
	private String name;
	private Timestamp creationtime;
	private String description;
	private int number;
	private short subnumber;
	private static final long serialVersionUID = 1L;
	
	public Project() {
		super();
	}
/*
  Omitted Accessors

*/
}

build, deploy, run in webservice navigator -> no problem.

Then i changed the UserSessionBean to:

[AT]Stateless(name="UserSessionBean")
[AT]WebService
public class UserSessionBean implements UserSessionLocal 
{
	[AT]PersistenceContext(unitName="DBAccess")
	private EntityManager em;
	
	public User doLogin(String login, String password)
	{
		Query query = em.createNamedQuery("doLogin");
		query.setParameter("login", login);
		query.setParameter("password", password);
		try
		{
			return (User) query.getSingleResult();			
		}
		catch(NoResultException e)
		{
			return null;
		}
	}			
	
	public Projecet testfunc()
	{
		return null;
	}
}

And now during deployment there is an warning (in reality it´s an exception) and the bean does not work any more.

The exception is

		1. Exception has been returned while the 'testproject.testcorp.de/testprojectear' was starting. Warning/Exception :
[ERROR CODE DPL.DS.6193] Error while ; nested exception is:

I already downgraded my Java JRE/JDK to 1.5.0_15 as it was hinted here in the forum, but the problem persists. Any idea what is wrong?
